Faster Fatties is a mod for The Witcher 3.

The mod speeds up large/huge enemies such as cyclops, golems, leshens, fugas, wyverns, as well as noon/nightwraith type enemies, grave hag type enemies (described as blazing fast in the bestiary), bears, and the lamia monster hunt boss.

It is made 50% faster, the value is picked from yrden's 50% slowdown.

Why this mod?

So that when the bestiary says you should use yrden to slow some of these monsters down, it actually makes sense.

So that their animations look more natural.

So that the biggest, most terrifying to look at enemies in the game aren't actually the easiest to dodge and kill.
